Battery Backup Solar Power Systems

Solar battery backup means you will have power when the grid is both up and down . All you need to do is create your own energy with the sun and store it in a solar deep cycle battery. This can be especially useful if you are in an area with an unreliable grid or that's susceptible to severe weather. Storing your own energy via battery backup means you will have the power you need—whether you are looking for a new solar system, have an existing grid-tied solar system or you are looking for a portable solar system to power lights and charge devices when the power is out. Browse our selection of battery backup options below to learn more.

Do you have questions about solar systems with battery backup or are you interested in retrofitting your existing grid-tied solar system? Give an altE solar expert a call today at 877-878-4060 and make sure you have power when the grid is down.

Our video about adding batteries to an existing grid-tied solar system will answer all of your questions about storing your own energy for when the grid is down. Watch to learn more!

Solar System with Battery Backup

If you’re going solar with a grid-tied solar system, adding battery backup is worth considering. Grid-tied systems are many times the easiest and most cost efficient type of solar system to install. But when the grid goes down UL requirements require grid-tie systems to shut down immediately so you aren't sending electricity to the grid and potentially endangering a lineworker.

Generally, battery backup doesn't mean powering your entire house. Rather you will identify a few "critical loads" (examples of critical loads: refrigerator, well pump, select lights, outlet for charging devices, etc.) you want to run in a power outage. Battery backup allows you to have all of the benefits of a grid-tied solar system and be able to have power during a grid outage.

The first step is determine your power needs. Check out our grid-tied solar calculator to get started. We have a couple of system options for you to choose from depending on your needs, so you are sure to find a grid-tied system with battery backup for you.
